5Power the RMC
This section describes two modes for powering the controller:
Battery mode: Power is supplied by a 12 volt battery with a charger (see section 5.2.)
External power mode: Power is supplied by an external power source (see section 5.3.)
Review section 5.1, follow the instructions for the appropriate power mode, then continue to section 5.4
Lithium battery.
NOTICE
– Equipment damage.
Power compatibility for TFIO modules depends on module
generation
:
Older green modules must only use 12 Vdc.
M2 modules and newer gray modules can use 12 or 24 Vdc.
A combination of green modules and M2 modules or gra
y modules must only use 12
Vdc.
5.1 Power on sequence
The RMC power on sequence is initiated as soon as power is connected. The following information may be
displayed on the LCD as the controller completes its startup:
ABB TOTALFLOW RMC-100: identifies the controller name and model
BOOT 2105412-XXX: indicates the version of the boot software
OS 2105411-XXX: indicates the version of the operating system
Super CAP Charged: indicates if the super capacitor is charged (see section 5.1.1.)
APP 2105457-XXX: indicates the flash version
IMPORTANT NOTE:
The scrolling duration of the displayed items may vary. When the
DATE/TIME displays, the power on sequence is completed.

18 | RMC-100 | 2105551MNAD
5.1.1 Super capacitor
The RMC design includes a super capacitor (Super CAP) that serves as a short-term power reservoir. The
first time that the unit is powered up, or if the RMC is left powered off for several hours or longer, the
boot time is approximately 2 minutes to allow for charging of the super capacitor. Once the capacitor is
fully charged, the boot time is considerably less.
IMPORTANT NOTE:
In the event of a loss of power or reset, the charged super capacitor
prevents the supply voltage from falling to zero for a short period of time (2.5 seconds).
This delay allows the system time to save all persistent data such as
trending, restart
configuration, etc.
5.2 Power with battery and charger
This powering mode requires a 12 volt (SLA) battery and a charger to recharge the battery. The following
instructions describe the typical installation of a battery and solar panel system as the charger. These
instructions should be adapted for alternate installations.
IMPORTANT NOTE:
Make sure the battery and charger meet the specifications
requirements
given in section 2.2.
5.2.1 Connect the battery (dc power)
The hardware required for a battery installation is a 12 volt sealed lead acid (SLA) battery and the
battery cable. Before installation, inspect the battery cable and connectors for breakage where they
terminate on the battery. To install and connect the battery:
1. Install and secure the battery where it will be used.
WARNING
– Bodily injury and property damage.Do not allow the battery terminals or
cable ends
, if attached, to come in contact with any metal surface. When the positive and
negative battery terminals contact a conductive material, this creates a short circuit and
could result in sparks, property damage, and possible explosion.
2. Connect the battery to the terminals (Figure 5-1). The power terminal block is green. Observe the
polarity (+ and -).
WARNING
– Bodily injury and property damage.All wiring of peripheral or external
devices to the controller should be com
pleted prior to applying power (connecting the
battery).
Connect the battery before connecting the charger cable.
Figure 5-1: Battery port
3. Confirm that the battery is supplying power to the RMC by observing the power on sequence
information scrolling on the LCD (see details in section 5.1). When the DATE/TIME display, the
sequence is complete.
4. If the power on sequence fails to initiate or complete, press the reset button shown in Figure 5-4.
5.2.2 Connect the charger
The RMC may use a solar panel (20 Watt or less) with Nominal 12 Vdc output voltage. The solar panel
may be mounted on a 2 inch pipe or the top or side of a meter house. Call the ABB main office number
BAT CHARGER/EXT PWR
Battery port

2105551MNAD | RMC-100 | 19
listed on the last page of this guide for questions about mounting the solar panel on the top or side of a
meter house.
NOTICE
– Equipment damage.
Alternate installations could use a power source instead of a solar
panel charger. When using a
power source, the output must be 14.5 Vdc to 15.5 Vdc maximum as
described in section
2.2.
Failure to use chargers that meet the required voltage specifications may cause equipment
damage.
Exercise caution when handling the solar panel to avoid damaging it.
For optimum charging, avoid placing the solar panel where it will be in shadows for any part of the day.
The hardware required to connect the solar panel to the RMC is:
One solar panel with an integrated cable
One solar panel mounting kit
NOTICE
– Equipment damage. Never connect the solar panel or alternate charger cable to the
RMC before the battery is connected to the BAT port (
Figure 5-1).
To connect the solar panel charger (adapt instructions if connecting to a power source as a charger):
1. Verify that the solar panel is operating properly before installation:
a. Check the solar panel using a digital voltmeter to verify polarity and output voltage. Voltage
varies depending on the amount of sun, angle to sun, etc.
b. If the measured output voltage is within the manufacturer’s specification as defined by the
specification sheet supplied with the panel, continue with the installation.
c. If the measured voltage is out of specification, call the ABB main office number listed on the
last page of this guide for a replacement panel.
2. Connect the solar panel cable to the CHARGER/EXT PWR terminals as shown in Figure 5-2.
Observe the polarity (+ and -).
Figure 5-2: Solar panel connection
3. Mount the solar panel facing up from the horizon at a 50°angle. For northern hemispheres,
position the solar panel facing south. For southern hemispheres, position the solar panel facing
north.
Clean the solar panel on a regular basis to ensure maximum charging.
Continue to section 5.4 Lithium battery.
5.3 Power with external power
